supervisor
				  ==========

Starts and restarts several "daemon" scripts with stdout and stderr redirected
into log files with timestamps added.

				 Name Heuristic
				 --------------

If supervisor is started as /usr/local/bin/start-something, configuration file
will will be loaded from /usr/local/etc/something/supervisor.conf.

To use this feature, use --enable-name-heuristic configure script option.


			    supervisor.conf sample
			    ----------------------

    logdir = /home/vir
    pidfile = ./supervisor.pid
    
    [first]
    cmd = ./tricky.pl first
    autostart = yes
    autorestart = yes
    restartdelay = 5
    log.timestamp = yes
    log.microseconds = yes
    
    [second]
    cmd = ./tricky.pl second
    autostart = yes
    autorestart = no


			configuration file parameters
			-----------------------------

`logdir` -- log files directory

`pidfile` -- pathname of file with supervisor daemon process identifier

`cmd` -- command line to start

`autostart` -- start command at supervisor startup

`autorestart` -- restart failed process after `restartdelay` seconds

`log.timestamp` -- add or not timestamp to log entries
